Abstract: 1,249,869. Hair washing apparatus. R. A. L. MOULARD. 29 Dec., 1969 [30 Sept., 1968; 19 March, 1969; 2 April, 1969, [Nos. 46208/68, 14431/69 and 17299/69]. Heading A5R. [Also in Divisions B1 and B2] Apparatus for washing hair in situ on the head of a human subject includes spray apparatus for producing alternating pulses of two distinguishable fluids, namely hot and cold water, mounted to spray said fluid impulses into a chamber defined by a cabinet. The cabinet has an aperture through which hair and scalp can be located in the chamber and the aperture includes sealing means for the head of the subject being treated. As shown in Fig. 11 the cabinet 77 has a neck rest 87, conveniently of molded plastic and an aperture 81 through which the head of the subject is located. Mounted in aperture 81 is a waterproof curtain 84 of resilient material for example a thin sheet of rubber, which is sealed to wall 80 and extends into aperture 81. A boundary surface 85 in curtain 84 defines a hole 86. Within boundary 85 is a draw-string 88 which is operated by means of winding mechanism 89. Removably attached to the boundary 85 of curtain 84 is cushioning element 90 of a soft resilient material, e.g. sponge rubber or plastics. In the interest of hygiene an individual element 90 may be used for each subject treated. As an alternative the boundary 85 may be fitted with an inflatable element. Included in the Specification is a flow diagram of a system for the automatic washing of hair (see Fig. 14 not shown). The system is "fail-safe", e.g. the hot water supply to the spray apparatus is cut off should the cold water supply fail. The spray apparatus (see B2F Abridgment may also be used for massage.

Title: Improvements in electric or other imitation candle or other flame lamps
IPC: F21S8/06
Filed: 1937-06-22
Abstract: 499,745. Imitation candle &c. lamps. BARTLETT, S. C. L. June 22, 1937, Nos. 17341 and 24981. [Class 75 (iv)] In an imitation candle or like flame lamp, the imitation flame element 11, Fig. 2, consists of vanes, made, for example of aluminium foil, which radiate from a common vertical axis and are so shaped as to present in elevation a flame like appearance. The element 11 is mounted at the upper end of a tube 8 which is formed to represent a candle and is carried by a reflector 5 surrounding and concealing a source of light such as an electric incandescent lamp 2, Fig. 1, or a gas mantle 60, Fig. 16. The inside of the tube 8 is polished to act as a reflector and it is formed on the outside with raised portions 10 to simulate dripping wax. In the form shown in Fig. 1, the element 11 is carried by a piece of aluminium wire 12 which is blackened to resemble a wick and to which are secured a pivot pin 13 and a counterweight 16, the former engaging in a bearing on a bracket 14 so that the ascending air currents produce a flicker effect. Fig. 5 shows a modification in which the flicker effect is obtained by mounting the element 11 on a light coil spring 35. As shown in Fig. 10, the tube 8 may be constituted by the upper opal part 25 of an electric lamp bulb which is formed with clear and silvered portions 27, 28 respectively and on which the element 11 is mounted, preferably by the engagement of the base of a supporting spiral spring in a recess in the upper end of the part 25. Fig. 13 shows the invention applied to a . chandelier carrying a number of imitation candles 52 on to the flame elements 11 of which the light from the concealed source 2 is directed by lenses 54. In the construction shown in Fig. 19, an imitation antique oil lamp is fitted, at the spout end 72 with a flame element 11 which is illuminated by an electric bulb 2 disposed horizontally within the reflecting body 71.

Title: Improvements in or relating to photo-electric devices for controlling the operation of machine tools
IPC: B23Q35/128
Filed: 1943-10-21
Abstract: 642,401. Photo-electric copying machines. SCHINDLER, W. Oct. 21, 1943, No. 17344. Convention date, July 14. [A Specification was laid open to inspection under Sect. 91 of the Acts, March 9, 1944.] [Class 40 (iii)] In a copying machine for machining a blank in accordance with a silhouette or similar drawing or photograph having an outline corresponding to the profile to be worked, the working tool is carried by a cylinder 4 which is rotatable on its axis and has its axial movement controlled by the output of the photo-cell 3 mounted on the cylinder and receiving a narrow beam of light from a source 1 mounted above the drawing. The amplified output from the cell excites the winding of a servomotor 9 which has a continuously driven armature, and rotation of the winding causes the opening of a valve 7 to admit fluid into the cylinder 4 which is thus forced away from a fixed piston 5 within the cylinder, against the action of a return spring. Valve 7 is only opened when cell 3 is fully illuminated. When the cell is obscured by a part of the drawing, servomotor 9 ceases to function and the cylinder 4 moves towards piston 5 again. At this point, the cylinder 4 is rotated slightly and another cutting movement takes place. In the Specification as open to inspection under Sect. 91 it is stated that the cylinder 4 may be fixed and the piston 5 movable. Also alternative arrangements are described comprising an electromagnet energized when the cell 3 is excited to attract an armature which may open a valve such as 7 or be connected directly to the cylinder 4. This subject-matter does not appear in the Specification as accepted.

Title: Apparatus for the visual representation of symbols on the screen of cathode ray tubes
Inventor: HOFFMANN EDELHARD
IPC: G09G1/12
Filed: 1957-06-03
Abstract: 864,024. Cathode-ray tube circuits. WERK FUR SIGNAL-UND SICHERUNGSTECHNIK BERLIN VEB. June 3, 1957, No. 17567/57. Class 40(7) A visual representation of numerals is displayed on the screen of a cathode-ray tube by producing appropriate Lissajous figures from sinusoidal voltages having a 1:2 frequency ratio and then blanking out unwanted portions by means of blanking signals dervied from 50 (or 100) c.p.s. sinusoidal voltages by rectification and phase adjustment under the control of a resistance-capacity network. As shown, the initial Lissajous figures are produced by supplying the vertical deflecting plates V (Fig. 1) of the tube with voltages derived from one of the terminals 1, 2, 3 (Fig. 1a), depending on the figure to be produced, these voltages consisting of a 50 c.p.s. sine wave (terminal 1); the positive half-cycles of this sine wave together with an adjustable amount of the negative half-cycles (terminal 2); and the negative half-cycles together with an adjustable amount of the positive half-cycles (terminal 3); and by supplying the horizontal deflecting plates H with either a 100 c.p.s. voltage from terminal 5 or the negative halfcycles of this wave from terminal 4. To complete the formation of a particular figure unwanted portions of the basic Lissajous figure are blanked out by applying blanking signals, selectively, from terminals 6, 8 or 9 (Fig. 1b) to the grid G of the tube, the cathode K being continuously supplied from terminal 7 and the phase of the blanking signals adjusted by means of variable resistors R 3  and R 5  to blank out the undesired portions. The fundamental steps leading to the production of the numeral 5 (Fig. 2e), which is produced by supplying the V and H plates of the tube from terminals 3 and 4 (Fig. 1) respectively and the grid G from terminal 8 (Fig. 1b) are described with reference to the component traces Figs. 2a to 2d.

Title: Self cleaning filter for liquids
IPC: B01D29/00
Filed: 1964-04-30
Abstract: 1,075,541. Fluid-pressure servomotor systems. J.T. RYMER. July 2, 1965 [April 30, 1964], No. 17924/64. Heading G3P. [Also in Division B1] In normal operation Fig. 1 (not shown) a pump 10 delivers liquid through passage 18 of a piston valve 14 to the inlet 21 of a filter unit 22 and thence to outlet pipe 24, but when the differential pressure across the unit 22 rises sufficiently (Fig. 2) a control valve 35 effects movement of the plunger 17 of valve 14 whereby the incoming liquid is delivered via groove 18a to line 28 leading to the back of a piston 27 in a reservoir 26 on the outlet side of the filter, whereby movement of the piston 27 effects reverse flow through the filter unit 22 and also maintains the outlet flow through pipe 24, the plunger 17 also connecting the inlet pipe 20 of the filter unit to a drain line 34 leading back to the sump 11 from which pump 10 extracts the liquid. The piston 38 of control valve 35 has an end of frusto-conical section, so that once lifted from its seat 39 by the excess inlet pressure, it exposes a larger area and moves rapidly to the position shown in Fig. 2 in which high pressure liquid is delivered via lines 52, 53, 48 to the lower end of valve 14, which was previously connected to drain via lines 48, 47, 46. Apart from the axial groove 18a and the through passage 18, the plunger 17 of valve 14 includes a through passage 30 connecting to an axial passage 31 by-passing at 32 the passage 18. In the Fig. 1 position passages 30, 31, 32 connect the lower end of reservoir 26 to the drain line 34, while in the Fig.2 position passage 31 connects filter unit inlet 20 to line 34. In view of the axial form of groove 18a, back flushing of filter unit 22 proceeds while plunger 17 is rising, until a further groove 57 connects groove 18a to line 60 whereupon high pressure liquid is delivered to a space above a second piston 63 in control valve 35 which initiates the end of the back flushing cycle. The resulting movement of piston 63 causes its rod 64 to engage the piston 38 pushing it downwards, the area of piston 63 exceeding that of piston 38 and piston 38 is reseated on seat 39. This results in the space 50 at the lower end of valve 14 being connected to drain as in Fig. 1, and the pressure in space 54 at the upper end of valve 14 effects a downward movement of the plunger 17, which when completed restores the parts to the state shown in Fig. 1 whereupon normal filtration flow is restored. An additional passage in the plunger 17 connects in the Fig. 2 position to a sludge outlet pipe 71 of the filter unit and subsequently in the Fig. 1 position to a sludge receiving tank 74, there being an arrangement for flushing the sludge passage in plunger 17 so that a quantity of sludge is removed from the unit 22 on each back flushing cycle. Reference has been directed by the Comptroller to Specification 965, 337.

Title: Gyroscopic erection system
IPC: G01C19/30
Filed: 1956-06-12
Abstract: 802,340. Automatic control systems for gyroscopes. COLLINS RADIO CO. June 12, 1956 [Oct. 12 ,.  1955], No. 18157/56. Class 38 (4). In a system for automatically erecting a gyro having a rotor mounted in a gimbal, a position-sensitive single-circuit switch mounted on the gimbal changes from on to off when the gimbal is in a desired position to reverse the sense of torque applied about an axis perpendicular to the rotor and gimbal axes and thereby restore the gimbal to its desired position by precession. As applied to a horizontal gyro, .tilt of the rotor bearing case about a horizontal axis is detected by a gravityresponsive on-off mercury switch which just makes when the rotor bearing case is horizontal or at any other desired angle. The case is then automatically maintained in this position by arranging the mercury switch to control a reversible two-phase induction torque motor precessing the gyro about a vertical axis. The motor is arranged to operate in one direction when the mercury switch is open and in the other direction when the mercury switch is closed. The resulting oscillation of the gyro is damped out by inertia effects. In one arrangement the motor torque is reversed through a two-pole relay, controlled by the mercury switch, connecting one or other of the motor phase windings directly to the power source. In another arrangement one motor phase winding is permanently connected to the power source through a capacity to produce torque in one sense and when the mercury switch closes, the other motor phase winding is connected directly to the power source to produce a torque in the reverse sense which more than balances that due to the capacity. In a further arrangement, Fig. 2, the mercury switch 22, when closed, directly connects motor phase winding A to the power source and, when open, permits current to flow through a control winding 38 of a saturable reactor 39 to reduce the impedance of a winding 40 and thus effectively connect motor phase winding B directly to the power source. In a still further arrangement, Fig. 4, when the mercury switch 22 is open, a voltage equal to that of the power source is applied to motor phase winding A through a transformer 42 to produce torque in one sense, and when the mercury switch is closed an opposing voltage double that of the power source is introduced into the supply to motor phase winding A so that the motor torque is reversed. In a modification of this arrangement transformer 42 is replaced by a direct connection to the power source. Application to vertical gyros and the use of thermionic and magnetic amplifiers is referred to.

Filed: 1948-07-06
Abstract: 644,955. Axial-flow and centrifugal compressors. POWER JETS (RESEARCH & DEVELOPMENT), Ltd. July 6, 1948, No. 18173. [Class 110(i)] In a multi-stage dynamic compressor having an intercooler, surging at low output is prevented by varying the degree of cooling in accordance with the load so that the ratio of the densities of the compressed fluid after and before cooling is increased when the load decreases and is decreased when the load increases. The temperature of the compressed fluid could be sub-atmospheric at part load, but preferably it is arranged to be approximately atmospheric at the lowest load and progressively higher at greater loads. In the embodiment shown, in which an intercooler 4 is interposed between two axialflow stages 1 and 2 mounted on a common shaft 3, the flow of coolant is controlled by a valve 8 in accordance with the speed of the shaft by means of a centrifugal or other speed governor 5. The governor may be linked to the valve by electrical, hydraulic or mechanical servo mechanism. In a modification, the valve 8 is operated by a capsule responsive to the pressure at the outlet of the low pressure stage 1. As a further alternative. the control may be responsive to mass flow. Instead of the valve 8, the pump supplying the coolant may be controlled. The compressor stages may be on separate shafts, the relative speed of which may be varied. The invention is applicable to centrifugal compressors. According to the Provisional Specification, the control may be in accordance with any two of the above-mentioned variable factors.
